A detecting unit detects an input signal and acquires likelihood values of respective binary data items included in the data. On the basis of reliabilities of the likelihood values of the respective binary data items acquired by the detecting unit, a scheduling unit draws up an operation schedule to execute an LDPC operation using the likelihood values of higher reliabilities with priority. On the basis of the operation schedule, an LDPC decoding unit executes decoding by executing the LDPC operation using the likelihood values acquired by the detecting unit.
